18: Prius C
For a short period, the Prius was the hottest car you could get. Of course, that was back in 2008 when gas prices were soaring and SUV models were all the rage. Sound familiar? Well, now there are plenty of fuel-efficient options to choose from, and the Prius has become a relic of the past. Sales numbers for the car have slipped dramatically and Toyota has attempted to revive the brand with a few different incarnations (via The Motor Digest).

The Prius C was supposed to be a model that would entice younger car buyers into the showrooms. Unfortunately, the car didn’t offer anything unique when you compare it to the countless other compact cars on the market. Where the Prius was once a technologically advanced compact car, nowadays it just uses an outdated design.
